Vedclass · Answer

(B) According to Kepler's second law (law of areas),the areal velocity $(A)$ is defined as the rate at which the area is swept out by the position vector of the planet.Mathematically,the areal velocity is given by the relation:$A = \frac{dA}{dt} = \frac{L}{2M}$where:$L$ is the angular momentum of the planet,$M$ is the mass of the planet.Rearranging this formula to solve for the angular momentum $(L)$:$L = 2 M A$Therefore,the correct option is $B$.

If $A$ is the areal velocity of a planet of mass $M$,its angular momentum is
